The prehistoric cemeteries at Gochang, Hwasun, and Ganghwa contain many hundreds of examples of dolmens - tombs from the 1st millennium BC constructed of large stone slabs. They form part of the Megalithic culture, found in many parts of the world, but nowhere in such a concentrated form. Les cimetières préhistoriques de Gochang, Hwasun et Ganghwa abritent des centaines de dolmens – sépultures faites d'énormes dalles de pierre datant du Ier millénaire av. J.-C. Ils appartiennent à la culture mégalithique que l'on retrouve en de nombreux autres endroits du globe, mais jamais en si forte concentration. تحوي مقابر غوشانغ وهواسونغ وغانغوا القديمة مئات الدلامن وهي قبور مؤلفة من شواهد حجرية ضخمة تعود الى الألفية الاولى قبل الميلاد. وتنتمي هذه الدلامن الى ثقافة الميغليث المتواجدة في أماكن متعددة أخرى من العالم إنما بكثافة أقل. На этих доисторических кладбищах находится много сотен дольменов – древних захоронений, относящихся 1-му тысячелетию до н.э. и сооруженных из больших каменных блоков. Эти памятники отражают культуру эпохи мегалита, которая может быть найдена во многих частях мира, однако нигде – в столь ярко выраженной форме. Las necrópolis prehistóricas de Gochang, Hwasun y Ganghwa albergan cientos de dólmenes –sepulturas construidas con enormes bloques de piedra– que datan del primer milenio antes de nuestra era. Estos monumentos forman parte de la cultura megalítica extendida por muchos lugares del mundo, pero en estos sitios su grado de concentración es mayor que en ninguna otra parte. De prehistorische begraafplaatsen in Gochang, Hwasun en Ganghwa bevatten vele honderden voorbeelden van dolmen. Dit zijn graven uit het 1e millennium voor Christus, gebouwd van grote stenen platen. Ze maken deel uit van de megalithische cultuur in vele delen van de wereld, maar nergens zo gevarieerd en in zo'n grote dichtheid als hier. Het Gochang dolmengebied (8,38 hectare) heeft de grootste en meest gediversifieerde groep dolmen. De Hwasun dolmen (31 hectare) liggen op de hellingen van een lage heuvelrug. Het gebied van de Ganghwa dolmen (12,27 hectare) bevindt zich op de berghellingen van het gelijknamige eiland. The Gochang, Hwasun and Ganghwa Dolmen sites contain the highest density and greatest variety of dolmens in Korea, and indeed of any country. Dolmens are megalithic funerary monuments, which figured prominently in Neolithic and Bronze Age cultures across the world during the 2nd and 1st millennia BCE. Usually consisting of two or more undressed stone slabs supporting a huge capstone, it is generally accepted that they were simply burial chambers, erected over the bodies or bones of deceased worthies. They are usually found in cemeteries on elevated sites and are of great archaeological value for the information that they provide about the prehistoric people who built them and their social and political systems, beliefs and rituals, and arts and ceremonies. The Gochang Dolmen Site (8.38 ha) features the largest and most diversified group, and is centered in the village of Maesan, along the southern foot of a group of hills running east/west. Over 440 dolmens of various types have been recorded in this location. The Hwasun Dolmen Site (31 ha) is situated on the slopes of a low range of hills, along the Jiseokgang River. There are more than 500 dolmens in this group. In a number of cases, the stone outcrops from which the stones making up these dolmens have been identified. The Ganghwa Dolmen Sites (12.27 ha) are on the offshore island of Ganghwa, on mountain slopes. They tend to be situated at a higher level than the dolmens of the other sites and are stylistically early, in particular those at Bugeun-ri and Gocheon-ri. The Gochang, Hwasun and Ganghwa Dolmen Sites preserve important evidence of how stones were quarried, transported and raised and of how dolmen types changed over time in northeast Asia. Criterion (iii): The global prehistoric technological and social phenomenon that resulted in the appearance in the 2nd and 3rd millennia BCE of funerary and ritual monuments constructed of large stones (the "Megalithic Culture") is nowhere more vividly illustrated than in the dolmen cemeteries of Gochang, Hwasun, and Ganghwa. A significant number of dolmens are distributed in each of the three areas, fully showing the development history of the megalithic culture with numerous examples of various style and type. The existence of a quarry near the site is especially important in providing references to the origins, nature and developmental history of the dolmens, as well as contributing to the integrity of the property. These components are all included within the boundaries of the inscribed property. The re-erection of selected collapsed or dispersed dolmens is planned. This work will be based on meticulous scientific research, in order to establish the original configuration and location of the dolmens. The greatest risk to the dolmens is fire and damage to the surrounding environment. The dolmens possess authenticity of form, materials and location. Most of the dolmens have remained untouched since the time of their construction, their present condition being the result of normal processes of decay. Although a few have been dismantled by farmers their stones have survived intact and their original location and form can be identified without difficulty. The entire area of the three separate sites has been designated as a Cultural Heritage site under the Cultural Heritage Protection Act, which requires that they be protected and managed accordingly. The sites and the area that extends 500 m from the boundary of the each site have further protection under the Cultural Heritage Protection Act as a Historic Cultural Environment Protection Area. Any form of development or intervention requires authorization and environmental impact assessment, and repairs must be carried out by licensed specialists. The sites are open to the general public. The properties belong to the Government of the Republic of Korea. Overall responsibility for protection, funding and the preparation and implementation of conservation policies for the sites and buffer zones rests with the Cultural Heritage Administration (CHA). The National Research Institute of Cultural Heritage carries out academic research, field survey and excavation (in association with university museums and private heritage research institutes). Day-to-day preservation and management is the responsibility of the relevant local administrations (Gochang-gun County, Hwasun-gun County and Ganghwa-gun County). The Gochang Dolmen Museum, Hwasun Dolmen Site Protection Pavilion and Ganghwa Historic Museum provide information about each dolmen site to visitors. Regular day-to-day monitoring is carried out and in-depth professional monitoring is carried out on a 3-to-4 year basis. Management plans have been developed for each of the three properties within the inscribed site. Their primary objective is the preservation of the original character of the dolmen sites and their immediate environments. The plans cover scientific research (survey, inventory, selected excavation and paleo-environmental studies), protection of the environment (selective clearance of vegetation cover, routing of visitors to ensure minimal impact on the natural environment, acquisition of adjacent farmland to prevent incursions, etc.), systematic monitoring and presentation (signage, access roads and parking, interpretation facilities, public awareness and participation of local communities, festivals and other onsite events). To prevent forest fire, scrubs near the dolmens are removed regularly and dolmens that have collapsed as a result of unearthed land or tree roots are investigated, extensively researched and restored to their original state.
